Scenario 2: If you have a CallPilot 5.0 1005r server and are adding the High
Availability feature, follow the instructions outlined in
Adding the High Availability feature to an existing CallPilot 5.0 1005r server"
(page 259)
servers as a High Availability pair.
After you make any changes to a High Availability configuration, the changes
must be transparent to the end users, including any existing CallPilot
Reporter, CallPilot Manager, Desktop, My CallPilot and Application Builder
installations, as well as the switch. To ensure this transparency, the ELAN
IP address, CLAN IP address, and host name used by the original CallPilot
server must be used as the new Managed (virtual) IP address for the pair
of High Availability servers. Because the Managed IP addresses and host
name are visible to the outside world, by reusing the current IP addresses
and host name, the changes to the server configuration are invisible to the
applications. New ELAN IP address, CLAN IP address, and host names are
required for both the original CallPilot server and the new CallPilot server.
All IP address and host name changes must be made before you import the
AutoStart definition file in order for the software to work correctly.
If you have an existing CallPilot 5.0 1005r server (running in a non-High
Availability configuration) you can perform a feature expansion to include
the High Availability feature. No additional hardware is required to add the
High Availability feature to a 1005r server, as all of the required hardware
comes preinstalled from the factory.
The procedure is the same as the new system installation procedure
documented in
(page
Before installing the AutoStart software on the existing server, new IP addresses
(CLAN and ELAN) and a new host name must be assigned to the existing
CallPilot 1005r server.
Providing a new host name and IP addresses is required to reuse the existing
host name and IP addresses as the Managed host name and IP addresses. As a
result, any existing users or applications can continue to access the 1005r server
without requiring configuration changes.
